Product details

Elevate the performance of your 2019–2021 Subaru WRX 2.5L with the AEM 21-863WR Cold Air Intake System. Engineered to unlock greater horsepower, torque, and throttle response, this high-performance system replaces the restrictive factory intake with a free-flowing, dyno-tested design. Air is pulled through an oversized AEM Dryflow synthetic air filter, offering exceptional filtration and airflow without the need for oiling. Strategically positioned to draw cooler air from outside the engine bay, the system helps reduce intake air temperatures and maximize combustion efficiency. The intake tube is crafted from mandrel-bent aluminum and finished in a striking wrinkle red powder coat for durability and a performance-ready appearance. Designed to work seamlessly with the factory emissions components, the AEM 21-863WR is easy to install using standard tools, making it a reliable and stylish upgrade for your WRX.
